Ukugaya nokuphenduka kwe-CNC kuyaguquguquka, kuyabiza futhi kunembile, nokho amathuba ezingxenye zomshini we-CNC anda nakakhulu lapho kucatshangelwa ukuqedwa okwengeziwe.Yiziphi izinketho?Nakuba lokho kuzwakala njengombuzo olula, impendulo iyinkimbinkimbi ngoba kunezici eziningi okufanele zicatshangelwe.
Amaphrojekthi we-Prototype
Okokuqala, yini isiphetho salokho?Ingabe ukuthuthukisa ubuhle noma ukusebenza?Uma lokhu kwakamuva, yiziphi izici zokusebenza okudingeka zithuthukiswe?Ukumelana nokugqwala, ukuqina kwendawo, ukumelana nokugqoka noma ukuvikela i-EMI/RFI?Lena ngeminye yemibuzo okufanele iphendulwe ngakho-ke, kucatshangwa ukuthi umklami uyazi ukuthi yiziphi izinjongo, ake sibheke izinketho ezihlukahlukene.
Iqedela Izingxenye ze-CNC Machined Metal Prototype
Eminyakeni engu-40 edlule, ochwepheshe bemishini bePrototype Projects baye bacelwa ukuba bakhiqize izingxenye ezivela ohlwini olukhulu lwensimbi ukuze zisetshenziswe ezimbonini eziningi.Imikhiqizo ikhishwa njalo, ihlanzwa futhi ihlanjululwe, noma kunjalo, ukukhetha kokuqedwa kubanzi kakhulu.
Namuhla, izinsimbi ezidume kakhulu zamakhasimende ethu i-aluminium alloy 6068, insimbi engagqwali 304 nensimbi engagqwali 316. Eqinisweni, lezi zintathu zicelwa kaningi ukuthi sibambe amasheya azo ngosayizi abahlukahlukene ukuze sihlangabezane nezidingo ze-Express CNC yethu yezinsuku ezintathu. isevisi yomshini.
Okusadumile kodwa okucaciswe kancane kakhulu ithusi, ithusi, ithusi le-phosphor, insimbi emnene, insimbi yamathuluzi.Ngezikhathi ezithile, amakhasimende acela izinsimbi ze-sepcial.Uma singathola okokusebenza futhi sikushicilele endlini, sizokwenza kanjalo, ngaphandle kwalokho sivamise ukuhoxisa umsebenzi kuchwepheshe okhethwe kunethiwekhi yethu yezitolo zemishini ezithenjwayo.Isibonelo, ama-alloy angavamile njenge-Inconel, i-Monel ne-Hastelloy avame ukudinga amasu athile kanye namathuluzi, ngakho-ke ngokuvamile sithola lokhu ngaphandle.
Insimbi ingaqedwa ngezindlela eziningi ezahlukene.Isibonelo, i-aluminium ngokuvamile ingaba i-anodised ecacile, i-hardcoat anodised, noma emnyama noma i-anodised yombala.Ukukhetha kuncike ekutheni imfuneko iwukuthuthukisa ubuhle noma ukusebenza (ikakhulukazi ukumelana nokugqwala noma ukumelana nokugqokwa).
Insimbi engagqwali imelana nokugqwala kodwa kwesinye isikhathi amakhasimende acacisa amanye amaqebelengwane.I-Electropolishing, ngokwesibonelo, ikhiqiza isiphetho sekhwalithi ephezulu kanye nokususa nokususa imiphetho ezingxenyeni eziyinkimbinkimbi.Ngakolunye uhlangothi, uma ubulukhuni bobuso, ukumelana nokugqoka noma ukusebenza kokukhathala kudingeka kuthuthukiswe, kokubili insimbi engagqwali engu-304 kanye ne-316 ingaba i-nitrocarburised noma i-nitrided.
Insimbi emnene izuza ngokukhetha okubanzi kakhulu kokuqedwa.Izinketho zifaka ukudweba okumanzi, umdwebo we-electrophoretic, i-powder coating, i-electroplating, i-chemical blacking, i-electropolishing, ukuqina, ukunamathela kwe-titanium nitriding (TiN), i-nitrocarburising, nokuqhunyiswa kobuhlalu, njll.
Ithusi nethusi kuvame ukucaciswa ezingxenyeni ezisebenzayo, ngaphandle kokuqedwa okwengeziwe okudingekayo ngemva komshini.Kodwa-ke, uma kunesidingo, izingxenye zingapholishwa ngesandla, zenziwe nge-electroplated, ziqhunyiswe umhwamuko, zifakwe i-lacquered noma ziphathwe ngekhemikhali emnyama.
Ukuqedwa okuchazwe ngenhla akuzona kuphela ezitholakalayo zensimbi nama-alloys.Sihlala sikujabulele ukuxoxa ngokuqeda namakhasimende futhi sizama ukusiza nomaphi lapho singakwazi khona.
Iqedela Izingxenye ze-CNC Machined Plastic Prototype
Njengama-aparts ensimbi, zonke izingxenye zepulasitiki thina umshini we-CNC ngokuyisisekelo zikhishiwe, ziyahlanzwa futhi zonisiwe kodwa, ngemva kwalokho, izinketho ezingaphezulu zivame ukuhluka.
Njengoba iningi lamakhasimende licela izingxenye zepulasitiki ezenziwe ngomshini we-CNC kungaba i-acetal (emnyama noma yemvelo) noma i-acrylic, sibamba izinhloboimpahla esitokweni.I-Acetal ayikwamukeli kalula ukuqedwa okwengeziwe, ngakho izingxenye ngokuvamile zinikezwa 'njengomshini'.
I-Acrylic, njengoba icacile, ivame ukupholishwa ukuze ibonakale esobala.Lokhu kungenziwa mathupha ngamamaki angcono alandelanayo e-abrasive, noma ngokupholisha ilangabi.Njengokwesicelo somuntu, i-acrylic ingapendwa ngopende we-acrylic noma i-vacuum metallised ukuze kuzuzwe indawo ekhanyayo kakhulu.
Okunye kwalokhu kulula ukukuqeda kunezinye, ngakho-ke wamukelekile njalo ukuxoxa ngezinto zokwakha bese uqeda nathi.Mayelana nepulasitiki, singasanta, sipende izingxenye eziyinhloko futhi sizipende, sizipholishe (ngesandla noma ngelangabi), ipuleti elingenagesi noma i-vacuum metallise.Kwamanye amapulasitiki anamandla aphansi, ukulungiswa kwendawo okukhethekile nge-primer noma ukwelashwa kwe-plasma kuyadingeka.
Ukuhlolwa Kwezingxenye Ze-CNC Machined Prototype
Isizathu esisodwa esenza amakhasimende akhethe ukuba nezingxenye ze-prototype ze-CNC eziphrintiwe kunokuthi ziphrintwe i-3D ukunemba okuphezulu.Ukubekezelela kwethu okucashuniwe kwezingxenye zomshini we-CNC kungu-±0.1mm, nakuba ubukhulu buvame ukubanjelwa ekubekezeleni okuqinile, kuncike ekwakhiweni, okokusebenza, kanye nejometri.Sihlola ngokuqinile ubukhulu, vele, amakhasimende angaphinda acele izici ezithile ezihloliwe.
Ngokuvamile izilinganiso zingathathwa ngama-calliper aphathwayo noma ama-micrometer kodwa umshini wethu wokulinganisa wokuhlanganisa (CMM) ulungele ukuhlolwa okuphelele.Lokhu kuthatha isikhathi futhi akutholakali ngesevisi yethu ethuthukisiwe ye-CNC kodwa kuyashesha kunokuthumela izingxenye kumuntu wesithathu ukuze zihlolwe i-CMM.Okuhlukile kuphela lapho kudingeka isimiso sokuhlola esiphelele, esihlelwe ngokugcwele se-CMM, noma ingxenye yezingxenye seyenziwe ngomshini futhi kudingeka ukuhlolwa okungamaphesenti angu-100.
Izinketho Zomhlangano zezingxenye ze-CNC Machined Prototype
Isizathu esisodwa ukuthi amakhasimende akhetha ukuba nezingxenye ze-CNC ezenziwe ngomshini kunokuba i-3D iphrintwe ukunemba okuphezulu.Ukubekezelela okuvumelekile kwezingxenye zomshini we-CNC kungu-±0.1mm, nakuba ubukhulu buvamise ukubanjelwa ekubekezeleni okuqinile, kuye ngento kanye nejometri.Sizohlola ngokucophelela zonke izingxenye ngaphambi kokuthunyelwa, futhi amakhasimende angacela izici ezithile ukuthi zihlolwe futhi.
Ngokuvamile izilinganiso zingathathwa ngama-calliper aphathwayo noma ama-micrometer kodwa umshini wethu wokulinganisa wokuhlanganisa (CMM) ulungele ukuhlolwa okuphelele.Kuyashesha kunokuthumela izingxenye kumuntu wesithathu ukuze zihlolwe i-CMM.Okuhlukile kuphela lapho kudingeka isimiso sokuhlola esiphelele, esihlelwe ngokugcwele se-CMM, noma ingxenye yezingxenye seyenziwe ngomshini futhi kudingeka ukuhlolwa okungamaphesenti angu-100.
